- The genome has a GC content of 36.41%.

## Abstract

Ammodendron bifolium, a rare deciduous shrub, is the only species of Ammodendron (Fabaceae) in China, which distributes in Huocheng county, Xinjiang. This study employed high-throughput sequencing technology to assemble the complete chloroplast genome sequence of A. bifolium. The entire length of chloroplast genome is 154,426 bp. It comprises 128 genes, which include 85 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The A. bifolium chloroplast genome has a GC content of 36.41%. Phylogenetic analysis strongly supported that A. bifolium is sister to the members of the Sophora genus. This study will provide the genetic information data for further phylogenetic studies of Ammodendron.
